' RECORD-1300K. I

To all whom it may concern:

Be it known that I, THOMAS M. Enron, a

State of Pennsylvania, have invented a certhe following is aspecification. The purpose of my invention is to produce a record bookin which any of the leaves of thebook can be placed in juxta-position toany other of the leaves in said book for com arison or any other desiredpurpose.

T e* further purpose of my inventionis secure one leaf of a book to themedial 'lli-ne of, an adjoin g' by hinged connection and. at suchdistance as to make it possible to bring the two leaves intosubstantially the. same plane and with either effective edge of oneadjoining the effective edge of the other. .fDhe further purpose of myinvention is tofsecure a plurality of leaves in orderfas fromleft toright,-in such manner that each shall bear a given relation to thenextin order, the successive relations of the several leaves to thoseadjoining them being identical, and be-capable of being broughtintosubstantiall the same plane with any other with the e ective' edgesofadjoining leaves substantially together. The structure may bearrangedto make either cover of the l the front cover when intended tobe Iprovide for y the" front-may be thrown opened in one direction only orso as to open from either end with equalfa'cility using either cover asfront cover at will. p

A further urpose of my invention is to tile use of either front or backof the first leaf as the actual front cover of the book, facing theinner front leaf-as normally folded either toward' or away from Thefurther purpose of my invention is to provide an extensible book 1nwhich all or any number of-the leaves may be brought into successivepositions. within substang tiall ;the same "lane and in which alloranynum erofthe eavessubsequent to a given. lefaf consideredeither from theback or freq;

While I have preferred to illustratemy invention by thoseforms thereofwhich have been found to be most desirable and practical n use, Irecognize that it is capable of application to a large variety of usesand in a large variety of embodiments and- I desire my illustrationtherefore not to be understood as representing all of the forms or allof the uses to which my invention is in-'. tended to apply.

Fig. 3 is an end elevation of the structure seen='in'-Figs. 1 and 2, in collapsed position. .Figs. 4 and 5-are top plan viewsof the structure seen-in Figs. 1,, 2'and 3, in different partiallyextended os'it'ions.

Ini'a'larg e variety of places where records are to be made in columns"representing. a a

all compared or relatin back to-- the same initial subject matter,difliculty is found in. following out the lines accurately to thecolumns, spaces or portions fartherremoved from the subject matter; tAnyspace and structure, extending the distance fromtlie name of] thegivensubject matter to the. column for the data or other material tobeinserted in respect .to it, renders thebook additionally liable toinjury because of the .95 greater space occupied and is unhandy and.

, awkward inuse for the same reason.-

M j invention is intended to obviate this" difli culty and hasbeen -aplied with great .ad-' vanta e to class .recor s forSunday school and .aied uses. H

It will be evident that the attachment need bemade along the medial lines only, as in Fig; 7, if desired, except as itmay be desirable in specific instance to support the first and lastsheets by further attachment of this portion to constitute a support,cover or backing for these sheets andto render,

the attachment of the foldable portions to the final leaves more secure.1

.My object-is to make each leaf in either direction, as may be desired,swing about approximately the medial lines 16 of the a djoining leavesand, as will be seen, except for convenience in operation and stiffnessof structure, it is not necessary that any other portion of the foldablestructure be attached to the leaf than that lying along the .approximately medial lines. I

I prefer to make the portlons 7, 9, 11,13, in case the left leaf is thepreferred leaf having the common structure thereon and form ing theeffective front of the book, of such length that when extended the edgesof the successive sheets shall lie substantially together, thoughevidently it maybe some what greater than this where a slight spacing isdesired, and somewhat less where the structure is improvedbyoverlapping.'In' either event, two effective hingesare provided at the medial lines16 and edges 17,

respectively, by which the structure can be collapsed wholly as in Fig,'3, or partially, or extended to any desired extent as in, Figs. 4 and5, each medial line16 affording a pivot about which the succeeding sheetor sheets may be extended to a position corresponding, with respect tothe preceding leaves, to the position ofv the. leaf whose medial line isused as the-hinge with. respect to these previous leaves.

collapsed, leaf 4 would be brou' ht into juxtaposition-with leaf lwhetlher leaf 5 be extend used with tended or colla sed; In this manner,any

arran' e-ment of eaves. may be secured in exposition which does nottranspose the initial position of the leaves considered.-

While any relative arrangement of the leaves extended can be secured bythe structure shown inFig. 1.. in which partsl l and 15 are attached,this doesrnot permit the last leaf 5 to be turned outwardly with itsback against the back of leaf 4, corresponding'to the permissibleposition of leaf 1 with'its back towardthe face of leaf 2, If'the portion 14 be freed from attachment to leaf 5 as far as the medial line,16, however, this shiftingof the last leaf tofturn it outwardly ispermissible. It might. be desirablein case of subject matter inwhich-the book 'could be etphal, facility with either. edge up and witheit 7 Thus, if leaves 1 2, and'3 are or page 5 or 1 representing-the voud evidently not be essential as the rel 'ative juxta-position of theleaves or sheets could be attained by the structure of Fig. .l.i

The extension of the part 6 to the outer edge18 of leaf 1 and of-thepart 15 to the outer edge 19 of leaf 5 provide complete protecting'covers for the leaves upon whichany desired subject matter can beimprinted or secured as at 20 for .titleor other desirable pur oses. v jT e facing shown at 20 may be of flexible material or compriserelatively stiff material, creased or otherwise weakened along themedial line so as to bend freely. Like; wise the foldable portions-6, 7,etc, may be of eitherflexible or stiff material, providing they permithinge-like action along the lines corresponding to the approximate edgeand able portions 7, 9, the underhalves of these leaves and the insideof the foldable portions or with the sheet- 5.

It will be evident that I have formed a collapsible book presenting anyof aseries of leaves injjuxta osition and capable of can be suppliedwith any suitable blanks, .data or surfaces to cooperate with each otherreversibility to ma e use ofeither inner cover page as the frontthereof, outside or inside, and offerin .leaves for comparison' -'or ineither direction.
